An optical amplifier is a device which receives some input signal light and generates an output signal with higher optical power. ជាធម្មតាធាតុចូលនិងទិន្នផលគឺជាធ្នឹមឡាស៊ែរ (កម្រមានធ្នឹមស្រាល ៗ ប្រភេទផ្សេងទៀត) ទាំងឃោសនាដូចជាធ្នឹម Gaussian ក្នុងទំហំទំនេរឬមានជាតិសរសៃ។ The amplification occurs in a so-called gain medium, which has to be “pumped” (ie, provided with energy) from an external source. Most optical amplifiers are either optically or electrically pumped.
